Disselhorst l believes that the ampulla acts as a seminal reservoir

 the rutting time. He suggests, further, that there is a relation 

 letween the state of development of the ampulla and the time occupied 

 bv copulation. When the organ is small or absent, as in dogs, cats, 

 and boars, the coition is a slow process, but when the ampulla is 

 large and well-developed, as in horses and sheep, the coitus occupies 

 a relatively short time.
